Calcium lignosulfonate based pulp waste as raw material, concentration and spray drying and made it excellent performance , low price, as an ordinary water reducer, applications are quite common. As the water-absorbent resin additives have not been reported . Calcium lignosulfonate graft superabsorbent is a novel hydrophilic group containing polymer network polymer material, which has strong water absorption . In this paper, calcium lignosulfonate graft superabsorbent targeted , systematic study of its preparation , morphology characteristics and soil moisture conservation agent as applied research . Thesis of synthetic calcium lignosulfonate graft superabsorbent process conditions , draw the amount of calcium lignosulfonate , initiator type and amount , type and amount of crosslinking agent , the amount of acrylamide , degree , dry conditions and other factors on the performance of high- absorbent resin washings were studied : further by orthogonal test , test systems obtained under optimum conditions (wt%): 47.9% of acrylic acid , acrylamide, 13.81% , 18.8%, calcium lignosulfonate , initiator, 0.39% , 0.19% crosslinking agent , 19.11% and in liquid , in this condition , to obtain a resin deionized water 1019g / g, 0.9% NaCl solution absorption capacity 111.2g / g. Using infrared spectroscopy , thermal analysis and scanning electron microscopy analysis of calcium lignosulfonate graft superabsorbent shape and structure . That calcium lignosulfonate graft superabsorbent good thermal stability was found on the composition of the copolymer superabsorbent decomposition temperature and surface morphology are characterized by the greater impact. Finally, the paper carried a superabsorbent surety agent in the soil with the application of the resin solution as insurance agent, applied directly to the soil , to work with acrylic acid / acrylamide absorbent resins, calcium lignosulfonate pick sticks absorbent resin in water retention capacity increased by 15% , the permeability of the soil can be increased significantly, and has the function of absorbing water repeatedly , also has good expansion, can reduce evaporation , especially to increase soil available water-holding , increase in temperature , increase soil permeability plays a significant role . New high water absorbency , high water absorption rate , salt , environmental protection, low-cost water-absorbent resin is bound to get a wider range of agricultural applications .
